A floor-standing air conditioner 1000 according to embodiments of the present invention will be described with reference to FIG. 1-FIG. 11. The floor-standing air conditioner 1000 may be an air conditioner with cooling function only. The floor-standing air conditioner 1000 may be also an air conditioner with cooling and heating functions certainly, namely, a cooling and heating machine. In the description of the application below, the floor-standing air conditioner 1000, a cooling and heating machine, is set as an example for description.

As shown in FIG. 1-FIG. 11, the floor-standing air conditioner 1000 according to embodiments of the present invention, e.g., a cooling and heating machine includes a body 1, an air duct assembly 2, a water container 3 and an air duct switching component 4.

As shown in FIG. 4 and FIG. 11, a body air inlet 11 and a body air outlet 12 are formed on the body 1, an air duct assembly 2 is disposed on the body 1 and comprises a fan 21, the fan 21 has a fan air inlet 211 and a fan air outlet 212, and the fan air inlet 211 communicates with the body air inlet 11, so that the fan air inlet 211 may intake air from the body air inlet 11.

As shown in FIG. 1-FIG. 8, a water container 3 is disposed on the air duct assembly 2, and a water tank 31 and a humidification component 32 (also referred to as a humidifier) are disposed inside the water container 3. An air duct switching component 4 includes an air outlet cover 41 and an air switching plate 42, and an air inlet 411, a first air outlet 412 and a second air outlet 413 spaced apart from each other are formed on the air outlet cover 41; the air inlet 411 communicates with the fan air outlet 212, and the air switching plate 42 is disposed on the air outlet cover 41; the air switching plate 42 may move between a first position where the first air outlet 412 is closed and the second air outlet 413 is opened and a second position where the first air outlet 412 is opened and the second air outlet 413 is closed. When the air switching plate 42 closes one of the first air outlet 412 and the second air outlet 413, the air inlet 411 communicates with the body air outlet 12 via another one of the first air outlet 412 and the second air outlet 413, where the humidification component 32 is disposed on the first air outlet 412.

It should be noted that the first position is a position status (not as shown in the figure) where the first air outlet 412 is closed by the air switching plate 42 and airflow is suitable for flowing to the body air outlet 12 via the second air outlet 413, and the second position is a position status (as shown in FIG. 1 and FIG. 5) where the second air outlet 413 is closed by the air switching plate 42 and airflow is suitable for flowing to the body air outlet 12 by the first air outlet 412. The air switching plate 42 may move back and forth between the first position and the second position, moreover, may keep still at anywhere between the first position and the second position according to requirements. At this time, airflow may discharge from both sides of the air switching plate 42, namely, partial airflow flows out of the first air outlet 412, and another airflow flows out of the second air outlet 413.

The water tank 31 may store a certain amount of liquid, e.g., water, etc., so that airflow may be humidified while flowing through the humidification component 32. The air inlet 411 communicates with the body air outlet 12 via the second air outlet 413, and airflow flows out of the second air outlet 413 when the first air outlet 412 is completely closed by the air switching plate 42 (namely, the air switching plate 42 is located in the first position), at this time, the airflow is not humidified by the humidification component 32 as not flow therethrough; when the second air outlet 413 is completely closed by the air switching plate 42 (namely, the air switching plate 42 is located in the second position), the air inlet 411 communicates with the body air outlet 12 by the first air outlet 412, and airflow flows out of the first air outlet 412, furthermore, the airflow is humidified by the humidification component 32 when flow therethrough; when the air switching plate 42 is located between the first position and the second position (exclusive of the above first position and the second position), airflow may flow out of the first air outlet 412 and the second air outlet 413, and at this time, partial airflow from the first air outlet 412 is only humidified, which achieves the purpose of airflow humidification similarly as well.

Therefore, airflow flows out of the second air outlet 413 and is not humidified when the air switching plate 42 is located in the first position, the floor-standing air conditioner 1000 may achieve non-humidified air discharge; when the air switching plate 42 is located in the second position, airflow may only flow out of the first air outlet 412 and is humidified by the humidification component 32 at this time and the floor-standing air conditioner 1000 may achieve humidified air discharge with the maximum humidifying capacity; when the air switching plate 42 is located between the first position and the second position, the floor-standing air conditioner 1000 may also achieve humidified air discharge, and at this time, the specific humidity of the discharged air may be adjusted according to actual demands accordingly. Here it should be noted that the humidification component 32 may be not only used to humidify the airflow flowing therethrough (e.g., air, etc.), but also have a cleaning function, specifically, the humidification component 32 may precipitate particulate matters in the air, thus refreshing the air.

It is appreciated that when the air switching plate 42 is located between the first position and the second position, the smaller the included angle between the air switching plate 42 and the plane of the first position is, the lower the humidity of the discharged air in the floor-standing air conditioner 1000 is; the larger the included angle between the air switching plate 42 and the plane of the first position is, the higher the humidity of the discharged air from the floor-standing air conditioner 1000 is.

According to the floor-standing air conditioner 1000 of embodiments of the present invention, the air duct switching component 4 is arranged in the fan air outlet 212 of the air duct assembly 2 and the humidification component 32 is arranged in the first air outlet 412 of the air duct switching component 4, such that a position of the air switching plate 42 is adjusted to adjust an airflow path and humidified or non-humidified air is discharged from the floor-standing air conditioner 1000, moreover, the humidity of the discharged air from the floor-standing air conditioner 1000 may be adjusted according to users' demands, thus improving users' experience.

As shown in FIG. 3, in some embodiments of the present invention, the water container 3 may be disposed on the air duct assembly 2 in a push-pull way, where the water tank 31 and the humidification component 32 may be detachably disposed inside the water container 3. Specifically, for example, the water container 3 may be pulled forward from the air duct assembly 2 (as shown in FIG. 3). At this time, the water tank 31 may be taken out of the water container 3, so that liquid, e.g., water, etc. is added to the water tank 31, and moreover, in case that the humidification component 32 is aging or fails, the humidification component 32 may be disassembled for replacement. The water container 3 may be pushed back to the right above of the air duct assembly 2 when there is enough water in the water tank 31, namely, the status of not pulling the water container 3 (refer to FIG. 5), therefore, it is easy and simple to handle, and it has reasonable layout.

As shown in FIG. 9, in some embodiments of the present invention, the water container 3 is detachably disposed on the air duct assembly 2. FIG. 9 shows a status of taking the water container 3 out of the air duct assembly 2, so as to be convenient for the supplementation of the water in the water tank 31, and for the cleaning of the water container 3. This arrangement allows for the water container 3 to be easy to handle.

As shown in FIG. 3-FIG. 9, in the floor-standing air conditioner 1000 of some embodiments of the present invention, the water container 3 and the air duct switching component 4 are disposed on the top of the air duct assembly 2, the fan air outlet 212 is formed on the top of the fan 21, the air inlet 411 is formed at the bottom of the air outlet cover 41 to be connected with the fan air outlet 212, the first air outlet 412 is formed on a side wall of the air outlet cover 41 and arranged vertically, and the second air outlet 413 is formed on the top of the air outlet cover 41 and arranged slantwise relative to the first air outlet 412. Thus, the layout among the water container 3, air duct switching component 4 and the fan 21 is more reasonable, moreover, the airflow has a shorter path, small flow loss and low noise in the process of flowing through the air duct switching component 4 from the fan 21.

It is appreciated that as shown in FIG. 3 and FIG. 9, when the water container 3 is taken out, the first air outlet 412 is open and the fan 21 communicates with the outside at this time, dust and other pollutants easily invade into the fan 21, the position of the air switching plate 42 is adjusted, e.g., the air switching plate 42 is switched to the first position to shield the first air outlet 412, so that the fan 21 may be protected by the air duct switching component 4, which effectively prevents dust, etc. from entering into the fan 21 via the air duct switching component 4, thus ensuring a clean airflow path, guaranteeing normal operation of the fan 21 and extending the service life of the fan 21.

As shown in FIG. 5-FIG. 8, further, the water tank 31 is located at one side of the humidification component 32 away from the first air outlet 412 and is spaced apart from the humidification component 32, thus guaranteeing the volume of the airflow while flowing through the humidification component 32, achieving a more compact structure between the water container 3 and the air duct switching component 4 as well as achieving a more reasonable layout among components.

As shown in FIG. 5, one end (e.g., a left end in FIG. 5) of the second air outlet 413 is adjacent to an upper end of the first air outlet 412, another end (e.g., a right end in FIG. 5) of the second air outlet 413 slantwise extends downwards away from the first air outlet 412. The configuration of the structure may effectively save the space occupied by the air duct switching component 4, and decrease the included angle between the plane of the first air outlet 412 and the plane of the second air outlet 413, which facilitates the outflow of the airflow from the air duct switching component 4, thus achieving the switch of airflow humidification status better, namely, the switch of the air discharge modes (humidified or non-humidified) can be achieved via rotating a smaller angle of the air switching plate 42 only; meanwhile, the structure is simple and has more reasonable layout.

As shown in FIG. 3 and FIG. 5, in some embodiments of the present invention, one end of the air switching plate 42 is located between the one end of the second air outlet 413 and the upper end of the first air outlet 412, moreover, the above one end of the air switching plate 42 is pivotally connected with the air outlet cover 41. The connection mode is simple, and the air switching plate 42 may be rotated to different angles conveniently, thus adjusting the mode of air discharge from the floor-standing air conditioner 1000.

Referring to FIG. 1 and FIG. 2, further, the air outlet cover 41 is provided with a motor 43, and the motor 43 is connected with the one end of the air switching plate 42, so as to drive the air switching plate 42 to rotate between the first position and the second position, which is easy to drive the air switching plate 42 for rotation accordingly. Moreover, the mode is simple and reliable.

Optionally, the humidification component 32 is a wet film, the wet film may absorb water from the water container, thus ensuring that the humidification component 32 is in a humidification status, and when air flows through the wet film, the wet film may precipitate particles in the air, thus keeping good humidification effect and refreshing air. The wet film may be prepared by adding special chemical raw materials to plant fiber or glass fiber, and it has good water absorption and evaporability.

It is appreciated that the humidification component 32 may be periodically taken out for cleaning and replacement, thus guaranteeing good humidification effect and air refreshing effect.

Optionally, referring to FIG. 10 and FIG. 11, the fan air inlet 211 may be further provided with a purification device 200, and at this time, the purification device 200 may be disposed upstream of the fan 21; the purification device 200 may purify and filter the air flowing into the fan 21 well, thus purifying the air and improving users' experience. Here it should be noted that the “upstream” may be construed as the upstream of the flow direction of airflow respectively.

As shown in FIG. 10 and FIG. 11, the floor-standing air conditioner 1000 includes an indoor heat exchange device 300 and an air handling device 100, and the air handling device 100 may be disposed below the indoor heat exchange device 300. The air handling device 100 may be further disposed above the indoor heat exchange device 300 (not as shown in the figure) certainly. The air handling device 100 includes the above air duct assembly, water container, air duct switching component, etc., thus humidifying the airflow flowing therethrough (e.g., air, etc.). Further, the purification device 200 may be arranged upstream of the fan air inlet of the fan, thus humidifying the airflow flowing therethrough (e.g., air, etc.).

The indoor heat exchange device 300 is used to cool or warm the airflow (e.g., air, etc.) flowing through the indoor heat exchange device 300, thus achieving the purpose of refrigerating or heating. The indoor heat exchange device 300 may have cooling function only, of course have refrigerating or heating functions at the same time. The indoor heat exchange device 300 may include a heat exchanger 320, an indoor heat exchange fan 310, etc. It is appreciated that the concrete structure and working principle of the indoor heat exchange device 300 have been well known to those skilled in the art, and thus will not be described in detail here.

The working process of a floor-standing air conditioner 1000 in one embodiment of the present invention is described in detail with reference to FIG. 1-FIG. 11:

Air flows into a body 1 via a body air inlet 11 and the body air inlet 11 communicates with a fan air inlet 211 when the floor-standing air conditioner 1000 works. Air enters into a fan 21 via the fan air inlet 211 and is purified by a purification device 200 at the fan air inlet 211, thus improving the air quality of the fan 21, protecting the fan 21 and extending the service life of the fan 21.

Under the action of the fan 21, air flows out of a fan air outlet 212, and the fan air outlet 212 communicates with an air inlet 411 of an air duct switching component 4. At this time, a position of an air switching plate 42 in the air duct switching component 4 may be adjusted according to user's actual demands, e.g., the air switching plate 42 may be adjusted between the first position and the second position, or in the second position when the floor-standing air conditioner 1000 is required to discharge humidified air, and when the air switching plate 42 is located in the second position, the humidifying effect is up to the maximum. When the air switching plate 42 is adjusted between the first position and the second position, the air gathers after flowing out of the first air outlet 412 and the second air outlet 413, and flows to the body air outlet 12 through an airflow path, thus flowing out of the body air outlet 12. The rotating angle of the air switching plate 42 may be adjusted according to the user's demand for the humidity of the discharged air from the floor-standing air conditioner 1000.

The air switching plate 42 may be adjusted to the first position, namely, the first air outlet 412 is closed when the floor-standing air conditioner 1000 is not requested to discharge humidified air. Thus, different humidity of air may be discharged and the air is purified, thus improving users' experience.
